Question

A 2.60 kg block is in equilibrium on an incline

of 24.3◦
.
The acceleration of gravity is 9.81 m/s
2
.
What is Fn of the incline on the block?
Answer in units of N.

Answer 1

W = m g = 2.60 * 9.81 = 25.5 N weight of block

Fn = W cos theta = 25.5 N * cos 24.3 = 23.2 N normal force of plane
